Stash your valuables where no one will ever suspect. Wall outlets are perfect for stashing valuables since you have tons of them at home. You must be crazy enough to search every household outlet for a secret stash. Probably, no one would even think of searching outlets! :)) BTW, it requires a digital key, such as an Arduino, to open the hidden outlet safe.
The Super Secret Key (a.k.a Suicide Key)
The vault features a key that no one would be crazy enough to insert. That's by plugging a 3 wired prong directly to the outlet! Talk about High Voltage suicide! The lock can only be opened by connecting an Arduino to the servo's pins (located in the outlet). Don't forget, we are using a dummy outlet so it's completely safe since it's not connected to the power-lines.
How Do You Open It:
Plug your DIY 3 pin cable from your vault to your Arduino (a.k.a Suicide Key) then connect your Arduino board to your PC (via USB). Upload the codes then press "CTRL + Shift + M" to access Serial Monitor. Enter "O" to open vault and "C" to close the vault's electronic latch. You can also open this by making a 555 PWM generator.
Influences & Inspiration:
This is probably another déjà vu experience to all Breaking Bad fans. You guys probably remember the scene when Walt hid the ricin capsule behind an electrical outlet during the "Live Free or Die" episode.
Tips & Reminders:
My 2nd version gave me a hard time since all of our wall outlets are embedded in solid concrete. Drywalls are easier to work with since it's easier to cut/ puncture. If you need a larger vault, multi-standard outlets and European outlets are bigger in size. This makes them much more ideal for stashing more stuff in one place.
